POCKET-SPACE STAMPING MACHINE.

Application filed September 27, 1927. Serial No. 222,326.

The invention relates to stamping devices, and particularly to an improved stamping device for stamping shirt fronts for indieating the correct position of the pockets, the object being to provide an improved stamping machine wherein a large number of fronts may be marked or stamped quickly and accurately.

Another object of the invention is to provide a pocket space stamping machine, wherein means are provided for holding in place a plurality of shirtfronts, together with means for successively and accurately stamping the fronts to indicate where the pockets are to be placed.

A further object is to provide a pocket space stamping machine wherein a shirt front is accurately stamped to indicate the position of one or more pockets, the structure being such that a minimum amount of manual labor is necessary to successfully operate the machine and manipulate the fronts being marked.

In the accompanying drawings- Figure 1 is a side View of a pocket space stamping machine, disclosing an embodiment of the invention.

Figure 2 is a top plan View of the structure shown in Figure 1.

Figure 8 is an enlarged fragmentary sectional view through the stamping mechanism forming a part of the present invention.

Figure 4 is a fragmentary sectional view' through Figure 3, approximately on line 4-4.

Figure 5 is a view similar to Figure 4;, but showing the parts in a different position.

Figure 6 is a plan view of a shirt front, 7 stamped and ready for receiving pockets.

Referring to the accompanying drawings by numerals, 1 indicates a suitable frame which is provided with uprights and horizontal members, together with bracing means of angle iron or other desired members. Arranged on the frame 1 is a platform 2 designed to receive a supply of shirtfronts 8 to be marked. As indicated in Figure 6, the fronts are substantially completed, except for pockets, and the machine embodying the invention is intended to place the marks d and 5 correctly on the fronts so that the workman may readily place the ill bar 3 pockets against the marks and then sew the-m permanently in position. The device is designed to be used preferably on workmens shirts, wherein the pockets are an outside or patch-pocket formation, and the pocket structure is merely sewed in place w thout cutting the shirt front. In the accompanying drawings, means have been shown for placing marks 1- and 5 on the fronts but it will be evident that one in rk or in than two could be provided, and that these marks could be adjusted to different positions as preferred.

After the shirts 8 have been placed on the platform 2. as shown in Figure 1, a comparatively heavy apertured bar 6 is placed c ely over p ns 7, said pins having aperr whereby locking pins 7 maybe inserted to hold the bar 6 in place whereby the shirt fronts 3 may be properly clamped 'tion. After the first front has been ed, it is pushed automatically toward b 6 so as to be out of the way of the second ma king. While the second marking takes place, the workman pulls the marked front 3 over bar 6 as shown in Figure 1. The second front 18 marked, automatically l over, and then manually turned over in the same manner. This is carried out until all of the fronts in the pile are properly marked. The marked fronts may then be removed and a new supply provided, and the operation repeated. In placing the fronts in position, the same are accurately positioned by reason of the various stops 8 which are adjustably mounted on the platform 9. and are clamped in the desired adjusted position by clamping screws 9 extending through suitable slots 10 and into the platf rm 2.

The printing structure is shown more particularly in Figures 3 to 5, from which it will be seen that there are provided side guides 11 and 12 preferably square in cross section. Tubular members 13 and 14 are fitted onto the guides 11 and 12 and to these tubular members are secured rods 15, 16, 17 and 18. These rods are preferably screwed into the guides 13 and 14 and locked against accidental removal by suitable nuts. The inner or adjacent ends of these rods are preferably screwed into a- Ushaped frame 19. and the rods are locked to this frame by suit able nuts as shown in Figure 3. At the (ill bottom, the frame 2 is provided with a presser plate 20 secured to the frame 19 by welding or in any suitable manner. This plate is provided with suitable openings 21 through which the stamping or printing members 22 move when the parts are moved to a printing or stamping position as shown in Figure 3. Within the frame 19 is an auxiliary U-shaped frame 25 carrying a supporting plate 26 on which the respective stampng or printing members 22 are mounted.

In operation, the auxiliary frame 25 moves up and down, and when in an upper position, receives ink as hereinafter fully described. In order to accomplish this action, a power shaft 2? slides loosely through the upper part of the o -shaped member 19 and is bolted or otherwise rigidly secured to the auxiliary frame Guiding pins 23 and 29 are riveted or otherwise rigidly secured to the auxiliary frame 25 and extend loosely through apertures in frame 19. Springs and 31 surround the guiding pins 28 and 29 and act to cushion the movement of the auxiliary frame 25 as the power rod 27 moves the same upwardly and then moves upwardly frame 19 and all the parts connected therewith. Springs 30 and 31 are comparatively short as shown in Figure 3 and, consequently, there will be an appreciable loose motion between the auxiliary frame 25 and the U-shaped frame 19. This permits the presser plate 20 to be forced downwardly against the fronts 3 for smooththe same and holding the same in place during the stamping or printing operation as follows shortly after the plate 20 has engaged the fronts 3.

[is indicated in Figure 4, a bracket 32 is riveted or otherwise rigidly secured to the U-shaped member 19 and, consequently, is stationary therewith. This bracket carries a pin extending through the ear 3 of the inking frame 35. This inking frame is provided with a longitudinal slot 36 and a *supporting bottom 37 }for supporting an inking pad 38-, which pad is almost vertical when the parts are in the position shown in Figures 3 and l, but is substantially hori zontal when functioning to ink the members 22. The auxiliary U-shaped member 24: is provided with a bracket 39 which is secured thereto in any desired manner and carries a pin 40 extending through slot 36. By reason of this structure, whenever the frame 25 moves upwardly, it will swing the inking pad 33 and associated parts so that the pad will strike the members 22 for ink ing the same substantially at the time the springs 30 and 31 come under tension. On the downward movement of the various parts, pin 40 swings the inking pad and associated parts to one side as shown in Figure 4. It will thus be seen that the up and down movement of the shaft 27 causes the inking pad to function, and also causes the printing or stamping members 22 to function to mark the various fronts 3. The

movement of shaft 2? is sufficient to raise the plate 20 an appreciable distance away from the fronts so that the automatic front shifting structure l1 may function. This structure is formed principally of L-shaped members 42 and l3 bolted or otherwise secured together at ll for presenting a substantially U-shaped structure when looking down upon the same as illustrated in Figure 2. A bolt or other fastening means which connects members 42 and 43 together, also comvcts them to a rearwardly extend bar or rod 45 having a downwardly ex iding portion 46 and a balancing portion 47 carrying a slidable weight 48. A rod or bar ll) is pivotally connected at 50 to the extension 4:6 and extends through suitable openings in the frame 1 and through a supporting strap 51 to link 52 to which it is pivotally connected at 53. Link 52 is also pivotally connected at 54- to a bell crank lever 55, said bell crank lever being pivotally mounted at 56 on a suitable extension from frame 1. The horizontal leg 57 of bell crank lever is provided with a stop or pin for limiting the movement of the pin 59 in one direction, said pin extending across leg 57. A retractile spring 60 acts normally to hold pin 59 against pin 58. Pin 59 is carried by a link 61 which is pivotally connected at 62 to the lever 63 pivotally mounted at 64: on a depending bracket 65 secured to the frame 1. platform 66 is secured to the end of lever 63 so that the parts may be operated by the feet if desired. A link 67 pivotally connects l ver 63 with lever 68, said lever 68 being pivotally supported by brackets 69. Lever 63 has an aperture through which the rod 70 loosely extends, said rod carrying a spring 71 bearing at one end against lever 68 and at the other end against a suitable stop, as for instance, a nut 72. Rod 70 is preferably curved in order to extend through lever 68 almost at right angles, said rod at the upper end being pivotally connected to the crank '73 by a suitable fitting 74. Crank 73 is rigidly secured to the gear wheel 75 which is continually meshing with the pinion 76 and said pinion is rigidly secured to a. pulley 77 driven by a belt T8, which belt is operated from any suitable source of power. The lever 68, by reason of the action of the rod 70, moves in one direction through power derived from the crank 73. Rod 70 pulls upwardly on one end of lever 68 and, consequently, forces the end 79 downwardly for pulling the link 80 downwardly. As link 80 moves downwardly, it will swing the lever 81 for pulling upwardly on the link 82, which is pivotally A foot pedal 01" llh lit"- connected with the shaft or-rod 27. In this so that a workman may quickly and accuway, the shaft 27 and associated parts hererately place the pockets in position and then tofore described, willbe moved upwardly. As this action takes place, link 61 will be pulled for moving leg 57 downwardly and the upright portion of the bell crank lever 55 toward the right as shown in Figure 1. This will cause the bell crank lever to pull link 52, rod 17, rod or bar and the members and 43 so as to force the same to the right in Figure 1. Each of the mem bers 4:2 and 43 is provided with a short spur 83 which projects a short distance into the top front 3, and when a movement is made as just described, the top front 3 is forced toward the bar 6 and is later swung over this bar by hand. As soon as the rod 75 releases lever 68, spring 84: will pull on bell'crank lever and quickly move the beret) and members 42, 43 and 44 back to their fo mer position, ready for the next operation. While these parts are moving back to their former position, the marking or stamping members 22 are moving downwardly to again function. This movement is caused by the spring 84: which swings a leg 57 upwardly and, consequently, swings the link 67 downwardly. The movements of these parts are sufficient to cause the stamping or printing structure shown in Figures 3 to 5 inclusive, to function. As the parts function, rod 27 moves upwardly and downwardly guided at one point by a bar 85 and through the sleeves 13 and 14 and bars 11 and 12. The bars 11 and 12 are braced and held in position by suitable bracing members 86 and 87, and the diagonal braces 88 and 89 connected to the upright structure 90. The lower ends of the bars 11 and 12 may be secured to the platform 2 in any desired manner, as for instance, by having the parts reduced, threaded, and a nut mounted on the threaded portion for clamping the bars in place.

In operation, when the parts are in the position shown in Figures 1 and 2, the machine is operating and the fronts 3 are being successively marked. hen all of these fronts have been marked and turned over the bar 6, the machine is stopped, bar 6 removed, and then the fronts transported to some other place. A new supply of fronts is placed in position shown by fronts 3 in Figures 1 and 2, and then bar 6 is slipped over the pins 7. The power may then be turned on and the marking operation continued for the second batch of fronts. hen the second. batch of fronts has been marked, they are removed and a third batch supplied, This is repeated as often as desir d. When fronts of a different size are to be marked, the various brackets 8 are shifted to properly center the new size fronts, and then the same operation takes place. In this way, the position of the Pockets is accurately determined stitch the pockets firmly to the fronts.
